Under Armour Seamless Stride 1/4 Zip Top Using levels of mesh mapped to your body, you get ventilation where you need it, plus the comfort of fewer seams. It's pretty much the most comfortable thing you'll ever train in. When you're working hard, your clothing needs to keep you comfortable. Crafted from soft knit fabric with body-mapped ventilation, this top will keep you at optimum levels of thermoregulation and is soft against the skin. The near sew-free construction means that you can move without worrying about chafing and irritation. The material is wicking and dries fast to keep you dry and comfortable while a quarter front zip assists in putting the top on and off and makes layering up a doddle. Anti-odour technology prevents the growth of odour-causing microbes, whilst reflective details enhance visibility in low-light conditions.
